If you follow the guidelines for a given cutter, you can exchange router bits and milling cutters as needed.
I use both/either in my Shopbot Buddy.
I tend to use my router bits more often than milling cutters as I am more familiar with the feeds and speeds.
One advantage router bits have is that most of them are not twisted and will not pull up the work from the spoil board.
My favorite cutter is an Onrud 52-910 spiral upcut but the upward spiral will pull thin stock off of the spoil board unless you have a vacuum hold down, but the results with this cutter are outstanding.
The one gotcha is making sure that when plunging into work make sure that the router bit can plunge, if the bit is not a plunge bit then you will need to ramp in to the work.
